UNITED STATES PATENT FFIGE.

WILLIAM J. RYGKMAN, OF BROOKLYN, ASSIGNOR TO HIMSELF AND FRANK B. BURT, OF NEW YORK CITY, N. Y.

IMPROVEMENT IN COMPOSITIONS FOR FIRE-PROOFING.

Specification forming part of Letters Patent N 0. 186,881, dated January 30, 1877 application filed December 18, 1876.

To all whom it may concern:

Be it known that 1, WILLIAM J. RYOKMAN, of Brooklyn, county of Kings, State of New York, have invented a new and Improved Fire-Proofing Compound, of which the following is a specification:

applied in a more or less concentrated solution, either by brushes with the common sizing, consisting of glue and whiting, to the scenery,

curtains, &c., or to the canvas or other fabric used for the same, or for dresses, 850., by saturating the same in the solution.

The composition imparts thereby to the fabric the quality of resisting the spreading of fire, as it is merely charred by exposure to fire, but does not burn.

The fabrics so prepared form thereby a reliable preventive of fire iu'theaters, and reduce the danger of fire to which such structures are exposed.

Having'thus described my invention, Iclaim as new and desire to secure by Letters Patent- I A sizing compound for fire-proofing fabrics and bringing out the subsequently-applied paint, consisting of equal parts of borax, alum, and muriate of ammonia, as described.

WM. J. RYOKMAN.
